Actually no. However, I have created other zones on ZFS pools. These zones run Oracle software that looks for available RAM before starting. If there is no RAM available, the software pukes out an error msg and dies.

I also found this link about limiting the amount of ZFS ARC in memory.

I'm just looking for ways to get these zones up and running while managing memory effectively. I'm also new at using ZFS and zones so I'm going through a bit of a learning curve too. Smilie

Any help is greatly appreciated.
